PIANO-PEDAL.

Specification o f Letters Patent.

Application led February 28, 1919. Serial No. 279,705.

To all whom 'it may concern.'

Be it known that I, JOHN GIGLIO, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Piano- Pedals, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to piano pedals and particularly to the method of mounting the same in connection with the base portion of the piano; and the object of the invention is to provide a simple and inexpensive construction of the class specied whereby the pedals may be quickly attached to or detached from the piano whenever necessary for the purpose of cleaning or repairs; and with this and other objects in view the invention consists in an apparatus of the class andfor the purpose specified, constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the Views, and in which :N

Fig. 1 is a sectional plan view of a part of the base portion of -a piano and indicating my improvement in connection therewith;

'Fig 2 a partial section on the line 2-2 of Fig. 1:

Fig. 3 a View similar to Fig. 2but showing only a part of the construction andon an enlarged scale and with other parts in section; l

Fig. 4 a partial section on the line 4 4 of Fig. 1 and on an enlarged scale and with part of the construction shown in Fig. 1 omitted;

Fig. 5 a detail perspective view of one of a number of springs which I employ; and,

Fig. 6 a partial section on the line 6-6 of Fig. 1 and on an enlarged scale.

In the drawing I have shown at 10 a part of the base portion of apiano and comprising a bottom member 11, a back 12, sides 13, one of which is shown, and a front base board 14 .having a plurality of openings 15 in the central portion thereof in which a plurality of pedals 16 are mounted.

In the construction shown, I have indi* cated three pedals, or the number of pedals usually employed in connection with a piano, and each of these pedals consist of a front foot piece 17 inwardly of which is a raised lug 18 and a depending lug 19,

and the inner end of the pedal is provided y with a head 2O in which is mounted a pin 2l, the opposite ends of which extend outwardly of the head to form trunnions 22.

I also employ a transverse bearing box 23, the top portion of which is provided with three spaced apertures 24 which open forwardly and backwardly through the boX, as clearly shown in Figs. 2 and 3, and formed in the top portion of the boX at the opposite sides of each of said openings are semi-circular bearing seats 25 having felt facings 26. A cover 27 is mounted on the top of the box 23 and guided by pins 28 in the opposite ends of the box, which lpins pass through said cover as clearly shown in Fig. 4, and said cover 27 is held in engagement with the box 23 by three bolts 29 located centrally of the rear end portion of the apertures 24, and which pass through elongated apertures 30 inthe cover 27, and on the upper end of which are mounted winged nuts 31 which also pass through the apertures 30 when in a position at right angles to that shown in4 Fig. 1.-

The cover 27 is provided on the bottom face thereof and in line with the semi-cir cular bearing seats 25 with similar bearings seats 32 which are also provided with felt facings 33. These bearing faces coperate with the bearing faces 25 to form a cylindrical bearing for the trunnions 22 on the head end 2O of the pedals 16, and the felt facings 26 and 33 vform cushioned noiseless supports for the'trunnions of the pedals.

At the front of each of the apertures 24, the box 23 is provided with a vertical recess or aperture 34 which forms web portions 35 in the boX member at the front of said aperture in connection with which the hook-shaped end 36 of a flat spring member 37 operates as shown in Figs. 2 and 3 of the drawing.

The bottom faces of the pedals 16 are preferably raised as shown at 38 and levers 39 are pivoted centrally thereof as shown at 40, one end of said levers being provided with downwardly directed cushion pads 41 and headed pins or bolts 42 are adapted to pass downwardly through the inner end.

portions of the pedals and operate in connection with the other portions 43 of the levers 39 as clearly shown in F ig. 3. The springs 37, or the end portions thereof, bear on the bottom portions of the pedals or the levers 39 pivoted therein, and serve to hold the pedals normally in a raised position and to raise the pedals into the normal position, after they have been depressed by the feet of an operator in the usual manner and in the depression of the pedals, the cushion pads 41 on the levers 39 operate in connection with the bottom 11 of the piano to limit the downward movement of the pedals.

I also secure to the top central portion of each of the pedals 16 levers 44, 45 and 46, the levers 45 and 46 extending to the left, while the lever 44 extends to the right, and the free end portions of the levers 45 and 46 are provided with arms 47 and 48 which operate in connection with vertical rods 49 and 50 secured to the free ends thereof in the usual manner. The levers 45 and 46 are pivoted approximately centrally thereof in a pivot block 51 having two compartments 52 and adapted to receive eac-h ofsaid levers and springs similar to the springs 37 are held in connection with the block 51 or the compartments 52 and 53 by the engagement of the hook end 36 of said springs with upwardly directed V- shaped portions 54 and transverse pins in the bottom portion of the compartments in said block. The levers 45-46 are held. in engagement with the block 51 by a transverse pin 56 which operates in V-shaped portions 57 in the top faces of said levers while other V-shaped portions 58 in the bottom faces of said levers operate in connection with the upwardly directed V-shaped portions 54 in the block 51, or the hook ends 36 of the springs. The construction and method of mounting one of the levers in connection with the pivot block 51 is clearly indicated in Fig. 6 of the drawing, and it `will be noted that the springs 37 operate to hold the inner end portions of the levers 45-46 in a raised position.

In the accompanying drawing I have shown the pedals in their operative position,- or connected with the box member 23, and when it is desired to detach said pedals from the box for the purpose of cleaning and making repairs or otherwise, the winged nuts 31 are first turned into a position at right angles to that shown in Fig. .1, after which the cover 27 is detached from the top portion of the box 23, in which operation the lnuts 31 pass through the elongated apertures 30.

The head end 20 of the pedals 16 may then be removed from the bearing seats 25 in the box member 23, after which the springs 37 may be removed, if desired.

i Fromthe foregeing it will bereadily understood that with my improved method of mounting pedals in connection with a piano, the pedals may be readily attached and detached whenever desired and with little or no labor, or loss of time, and while I have shown certain details of construction for carrying my invention into effect, it will be understood that I am not limited to these.

details, and various chan es therein and modifications thereofmay e made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
